20140254630 | Single Wire Analog Output Sensor Architecture - A analog integrated sensor device has an interface with only a single ground line and a single signal line configured to receive power and output an analog value. A power capacitor is coupled between the ground line and the single signal line. An analog sensor circuitry is operable to be powered by the power capacitor and further operable to output an analog output signal on the single signal line once the power capacitor has bee charged sufficiently. | 09-11-2014 |

20130015869 | TEMPERATURE MEASUREMENT OF ACTIVE DEVICE UNDER TEST ON STRIP TESTERAANM Francisco; RonaldoAACI ChandlerAAST AZAACO USAAGP Francisco; Ronaldo Chandler AZ USAANM Wong; Chi LungAACI GilbertAAST AZAACO USAAGP Wong; Chi Lung Gilbert AZ USAANM Messang; TimAACI GilbertAAST AZAACO USAAGP Messang; Tim Gilbert AZ USAANM Aberra; Ezana HaileAACI ChandlerAAST AZAACO USAAGP Aberra; Ezana Haile Chandler AZ US - A plurality of devices under test (DUT) are arranged in a strip tester having a temperature controlled heater block. Each DUT has a respective set of electrical test probes and a thermally conductive test probe for electrically and thermally coupling, respectively, of the strip tester to the DUTs. Temperature measurement of each of the plurality of DUTs is performed by a temperature measuring device. The temperature measuring device can be part of the test board of the strip tester and will be in thermal communications with the DUT through the thermally conductive test probe, or temperature of the DUT can be measurement with an RTD embedded in the thermally conductive test probe, thereby providing faster thermal response time. | 01-17-2013 |
